The NWA's technical team will be dispatched to flood-damaged sections of Portland on Tuesday.
In a release, the NWA said the team will accompany Daryl Vaz, Minister without Portfolio in the Ministry of Economic Growth and Job Creation, on a tour of areas damaged by flood rains last week.
More than thirty roadways in the parish were affected by rainfall from January 4 to January 9.
At least one roadway, Bourbon to Maidstone, remains impassable.
The NWA said the team is expected to generate solutions for the repair of the damage estimated to cost more than $140 million.
